Perhaps you should try some spelling variations:
nhung cong » dung cong, thong cong, hang cong
hoc thieu » hoc hien
chinh sua » chinh su, chinh cua, chinh luan
sua nhung » cua nhung, qua nhung, chua nhung
cong dan » cong san, cong tan, huong dan
dan toan » van toan, dan than, manh toan
toan cau » toan cao, toan ban, toan tap

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((hoc thieu) OR (toc thieu)) tinh - hanh chinh sua nhung cong dan toan cau~".
• Adding a wildcard symbol may retrieve word variants: ((hoc thieu) OR (toc thieu)) tinh - hanh chinh sua nhung cong dan toan cau*.
